How does damage assignment work when defending against events with multiple units?

Ruling: Each player sums up their total might into a single pool, then assigns damage from that pool to event units one at a time in any order they choose, assigning lethal damage to each unit before moving to the next.

Sequence:

• Sum all your units' might into one total pool
• Choose which event unit to assign damage to first
• Assign lethal damage to that unit
• Move to the next event unit and repeat
• Continue until all damage is assigned

Nuances:

• You must assign lethal damage to a unit before moving on to another unit
• Don't think of damage as coming from individual units, but as one combined pool
